over 80% of the oceans remain unexplored
and
untouched there's a reason for that of
all the environments that support life
on our planet the most forbidding and
remote are the Deep Oceans Where the
furthest reaches lie more than 6 miles
below the waves our ocean is the basis
for life on this rock and we are
impacting it in ways we don't even begin
to understand and the first step is
always
exploration the more you understand the
ocean the more you love the ocean the
more you're fascinated by it the more
you'll fight to protect
[Music]
it urgency to combat climate change here
we go has spurred new efforts to explore
ocean
depths sub is extremely
maneuverable imagine a craft that allows
you to explore a part of our world that
you simply couldn't see any other
way engineering a safe submarine is
extremely
challenging and mistakes can be
fatal catastrophic implosion the
unthinkable became all too real in 2023
the world was horrified by the implosion
of the Ocean Gate Titan submersible that
was on an expedition to explore the
Titanic the disaster killed five people
including ocean Gate's co-founder
stocked in rush I've been safely down to
the Titanic recite 33 times and to me
the idea that that lives could be
claimed by an implosion in this day and
age is almost unfathomable it was a bad
idea and they were worn the carbon fiber
used in the hoe may have been a critical
fail point the material is prone to
buckling Under
Pressure especially when combined with
the elong pill
shape but that was the Titan not to be
confused with the Triton
submersible being manufactured in
Sebastian
Florida Triton's design approach is
rigorous here Engineers are building
Subs designed to take non-sp Specialists
hundreds and even thousands of feet
below the surface
safely Patrick laty is the co-founder of
Triton
submarines safety begins with design it
carries all the way through to the
selection of materials the formation of
those materials into Parts those parts
made up into assemblies those assemblies
then tested and validated on their own
then incorporate into the complete
vehicle which is then tested
again if you're an engineer it is your
responsibility to do things in a manner
such that the end product is safe
because at the end of the day people are
relying on you to make a safe
product alt together their subs have
logged tens of thousands of hours
underwater without any
incident increasingly the vehicles are
being used for scientific research film
making and underwater
exploration so this is our most compact
3ers sub pilot sits in the back two
passengers in the front they have this
incredible completely unobstructed view
from this acrylic pressure
boundary the pressure boundary is a
perfectly round plastic orb that is
transparent it's like being in a
goldfish Bowl only the fish are on the
outside and the people are on the inside
and it's
invisible you really feel like you're a
part of the
ocean the boundary's main job is to keep
occupants safe from the crushing water
pressure pushing in from all
sides a sphere is one of the strongest
shapes in nature a spherical Hull
experiences the same amount of pressure
at every point on its surface minimizing
the chances of structural
failure so far the only Subs that have
made it to the bottom of the Mariana
Trench more than 6 mil below the surface
carried their passengers in spherical
enclosures and all were made of metal
like Steel or
titanium test test we good on audio
you're getting a good film director and
Ocean Explorer James Cameron who is an
investor in Triton wants more people to
experience the Deep the way he has the
goal of Triton Subs is to make the best
commercial which also means scientific
Subs in the world and to make them
widely available in 2019 a Triton
titanium spherical enclosure sub
completed one of the most ambitious
Global Expeditions in modern
history taking people numerous times to
the deepest spot in each of Earth's five
oceans 7 at including the Challenger
Deep in Mariana
[Music]
Trench the geometry of a sphere limits
its usable
space the designers wanted to increase
the number of passengers beyond what a
sphere could reasonably hold so they
settled on an elongated
shape made from a common yet deceptively
strong
material
acrylic acrylic is an incredible
material it's completely transparent
unlike glass where even after 6 in
you're starting to see quite significant
discoloration increasing the thickness
of the acrylic increases its strength
and ability to resist the pressure of
the water while retaining
visibility it's completely different
from anything that's preceded it we
wanted to be able to put the most people
into the smallest volume possible when
it's complete this sub will hold up to
nine people including a pilot they call
it Ava it's designed to safely dive
depths of up to 600 ft the unusual shape
is the the work of engineering firm dark
ocean and their principal designer John
Ramsey to accommodate nine passengers
it's incredibly difficult to do that in
a in a traditional sphere the way the
669 ARA works is it it just takes that
sphere and it optimizes it for the
passengers Inside by stretching it out
and allowing everyone to sit side by
side down into Worlds never before seen
this design draws from Decades of
research on acrylics there's an 800 page
kind of Bible of submersible acrylics
and you can go through and see every bit
of testing that was done the material
that makx is possible is acrylic
plastic everything you do in engineering
is based on what other Engineers before
you have done if somebody's got a great
elegant solution why reinvent the
wheel at the factory the team is
attempting tempting to attach Ava's
pressure Hull to its steel chassis
they've never had to maneuver a shape
like this okay uh Chris bring yours up a
little
[Music]
bit one slipped and the acrylic could be
damaged or scratched 1 2 3 this corner
the team positions the metal chassis
beneath the elliptical Hull it needs to
go towards you a little bit Monroe she
is such a l ready one
that doesn't look bad let's just keep a
little bit of tension on it yeah has
tension so despite the best efforts of
the engineers all there we go all right
there are still small adjustments to be
made so we're trying to thread in this
big pin now some of the bits of machine
to within a tenth of millimeter or less
to to get that nice fit come back Monroe
a little bit whoa whoa whoa go hold
tension it's slipping all
right give me a freaking heart
attack I mean it's so freaking
[Music]
close it's not going to go anywhere
right now so just come down on your
forks Monro okay tilt
forward okay back up okay the acrylic
Hull is secure for the moment but
they'll have to stop for the day to
tweak the size of the screws
does it always go according to plan no
am I really pleased with how far we've
got today oh
yes when we're solving problems when
we're building things we're engaged in
this process of getting our hands dirty
and actually doing some trial and error
testing to see if what we've we've built
was effective if it
worked testing needs to be particularly
rigorous when lives are at stake you are
implicitly relying on the people who
designed it and built it to make sure
that they've thought about how it can
fail and if they've come up with ways to
get around that today every new vehicle
be it a car airplane or submarine is
subjected to thorough testing and review
throughout the Engineering
Process the true Testament to its
reliability ultimately hinges on
obtaining certification from an
independent third party
they make sure that your assumptions are
not flawed that you're not doing
something that could be dangerous that
it complies with an internationally
recognized set of
rules the failed Titan submersible was
never officially
certified if you're putting passengers
on a sub you need it to be qualified by
some independent body whose job it is to
make sure that that vehicle is safe
[Music]
inter if there's any water angress in
there we are going to try to launch just
before the Ava sub is now ready for its
first dive senior approval engineer
ionel Dari is on site today for final
checks of all the sub's vital systems
making sure the submersible is safe for
passenger Dives down to 600 ft
everything went great we can issue the
final certificate for this
sumera after getting the green light the
sub is ready to make a shallow
[Music]
dive top side top size um hat is closed
light support is on a good you have
permission to
drive on our way on our
way amazing I mean this is the first
time I've been down and it's been um 2
and 1 half years of work this is the
result and it's a magnificent one really
loving
this if Triton is able to fulfill its
mission of building more submersibles
many others will soon be able to have
their first ride into the deep
ocean this is this other universe that
is most of our planet and it's such a
magical
place and to be able to now explore it
in Comfort is a phenomenal ability that
is open to more and more people that on
the
